I've just been playing with a program which does this for Maildirs (rather
than mboxes), by qmail's Dan Bernstein:
http://cr.yp.to/serialmail.html - requires
http://cr.yp.to/ucspi-tcp.html
It picks the envelope from Return-Path: and Delivered-To: headers. To make
it work with exim you need to patch it to use Return-path: and Envelope-to:
respectively (note that it's case sensitive!) Furthermore, if the SMTP
server to which it is delivering gives a 5xx response, it tries to bounce it
by invoking "qmail-queue" which obviously doesn't exist on an exim system
:-)
It's patchable (see below), but I wonder now whether it might be simpler
just to write a perl script which extracts the envelope headers and passes
the message back to exim with a different config file...
